Tewkesbury STW Wastewater Treatment Plant, Gloucestershire, England

Tewkesbury STW is a wastewater treatment plant located on Lower Lode Lane in Tewkesbury, Gloucestershire, England. It serves a population of approximately 26,045, placing it in the medium agglomeration category under UK regulatory frameworks. The plant is situated near the confluence of the River Severn and River Avon, making its discharge point ecologically significant. As a UK wastewater facility, Tewkesbury STW operates under the Urban Waste Water Treatment (England and Wales) Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations serving between 10,000 and 100,000 people, secondary treatment is typically required, with more stringent tertiary treatment if the receiving water is designated as sensitive. The plant discharges into the River Severn catchment, which flows into the Bristol Channel and ultimately the Atlantic Ocean. The River Severn is the longest river in the United Kingdom and supports diverse aquatic life, including salmon and eel populations. The surrounding area is predominantly rural with agricultural land use, and the plant plays a key role in protecting water quality in this important river system.

Tewkesbury STW discharges into the River Severn catchment, near the confluence of the River Severn and River Avon. The River Severn flows south-west through Gloucestershire into the Bristol Channel, a major estuary with significant ecological importance. The Severn Estuary supports migratory fish species and extensive mudflats that are vital for bird populations. The plant's discharge must meet quality standards to protect these downstream habitats from nutrient enrichment and pollution.
